LD1086

1.5 A adjustable and fixed low drop positive voltage regulator

Datasheet

production data

Description

The LD1086 is a low drop voltage regulator

capable of providing up to 1.5 A of output current.

Dropout is guaranteed at a maximum of 1.2 V at

the maximum output current, decreasing at lower

loads. The LD1086 is pin-to-pin compatible with

older 3-terminal adjustable regulators, but has

better performance in terms of drop and output

tolerance. Unlike PNP regulators, where a part of

the output current is wasted as quiescent current,

the LD1086 quiescent current flows into the load,

increasing efficiency. Only a 10 µF (minimum)

capacitor is needed for stability. The device is

available in a TO-220, D²PAK, D²PAK/A, DPAK or

DFN8 (4x4) package. On-chip trimming allows the

regulator to reach a very tight output voltage

tolerance; within ± 1% at 25 °C. The LD1086 is

available as automotive grade for adjustable

output voltages in the TO-220 and DPAK

packages. The PAT, SYL, SBL statistical tests

have been performed, and the devices are

qualified according to the AEC-Q100 specification

for the automotive market in the temperature

range of - 40 °C to 125 °C.
